Properties and Detection of Sound
14.4I can define,
analyze, and solve problems
involving sound behavior.
RefractionSound waves bend when parts of the wave fronts travel at different speeds. This bending of sound is called refraction.
BeatsWhen two sound waves of different frequency approach your ear, the alternating constructive and destructive interference causes the sound to be alternatively soft and loud a phenomenon which is called "beating" or producing beats.
Sound Waves
14.4 Sound Behavior and the Doppler Effect

Sound Waves The Doppler EffectThe Doppler Effect describes the change in frequency of a wave for an observer moving relative to the source of the wave.
The Doppler Effect
d detectors source
= (524 Hz) ( )343 m/s 0343 m/s 24.6 m/s
= 564 Hz
5. A trumpet player sounds C above middle C (524 Hz) while traveling in a convertible at 24.6 m/s. If the car is coming toward you, what frequency would you hear? Assume that the temperature is 20°C.
